This invention relates to a material moving machine to be moved over the of the ground and operable to scrape .up material therefrom, to transport a collected load, of material 5 and to discharge or unload the transported load, each of the operations being under the control of the machine operator. Machines heretofore used for such purposes in respect to the transporting of the load may be placed'in the following two 10 classes: those which have ground wheels; and

those having no ground wheels or equivalent supporting means. Those having wheels either carry the entire load of material or a part thereof on the wheels. Those without wheels drag theentire load over the ground. The dirt is commonly collected and transported in a container known as a bucket or scoop and these scrapers without wheels drag the bucket or scoop over the ground totransport the 0 load from one place to another. Wheeled scrap ers which do not support the entire load act partially as a drag scraper.

Those machines having wheels to carry the load require a frame structure which must be 5 strong enough to suspend the bucket or scoop with its charge of material. In large capacity machines, four wheels are commonly used. In smaller capacity machines, two wheels commonly .disposed at thesides or rear amused and thefront of the frame is supported on the rear of a tractor.

Obviously since the load in the type of scraper having, no wheels is not supported by the frame but by the material container itself, the frame structure may be much lighter in weight than that of a wheeled scraper. It follows that the expense of and attention to wheels, bearings and associated parts is saved. However, the drag scraper is not as easily drawn as that having wheels or .rolling supports.

- It is the primary object of this invention to provide a material or dirt moving machine including a container acting as a drag scoop or bucket during loading and as a roller during transportation of the load. It is another object of this invention to provide a structure of the character described having a drum like container and a shutter arranged to open and close a peripheral opening therein and when closed to form a complete substantially cylindrical surface mounted to be revolved and serve as a ground roller carrying the load. v

A further object of this invention is to provide a machine 'of the character described wherein power is transmitted to the shutter from the draft or traction device to open or close the latter.

A still further object of this invention is to provide a machine of the character described wherein the material receiving edge of the container may be adjusted in relation to the surface on over which the container is drawn and such adjustment obtained by power transmitted from the draft or traction device.

These objects together with other objects and accomplishments pertaining to details of strucas ture are obtained by the embodiments of my invention illustrated in the accomp yin drawings, in which:

Figs. 1 to 1 inclusive illustrate one embodiment of my invention: Fig. 1 is a side elevational view 1. of a material mover with parts in skidding position; Fig. 2 is a-planrview of the structure shown in Fig. 1, substantially one half of the structure being shown, the other half being duplicated; Figs. 3,4 and 5 are side elevational views on an 15 enlarged scale showing parts in digging, transporting and dumping positions respectively; Fig.

Referring more particularly to the drawings and the embodiment of the invention shown in Figs. 1 to 7 inclusive, a frame is shown comprising side bars 20, a rear bar 21, front bar 22 and draw bar 23. This frame may be in general of a conventional type and made upof structural steel bars of suitable shapes, welded, riveted or otherwise secured together. As the structure of the scraper is duplicated on opposite sides, only one half is shown in Fig. 2 and only one half of the duplicate structure is described. A. fragment of m a tractor for drawing thescraper is indicated by T. Secured to the side bars 20 are bearing blocks 24 in which'trumiions' on the bowl or container 25 are journalled.

The bowl or container 25 comprises a sectional cylindrical shell 26 with an axially extending opening 27. End plates 28 of circular form are secured toshell 26. At one margin of the opening is a digging or material receiving plate 29. As is common in bowls which are rolled to obtain various positions of the material receiving edges, shoes 30 are provided peripherally spanning the opening 27. These shoes may be bolted or otherwise securedto end plates 28. Trunnions 31 are fastened to the end plates 28 and are journalled in bearing blocks 24 so that the bowl or container 25 may be revolved.

A shutter 32 for the container 25 comprises a sectional cylindrical wall 33 and sectoral end plates 34 with a central circular portion partially bounded by an outstandingrail 35. This rail may be a channel bar secured to end plates 34. Rail 35 has a gap 350.. Shutter 32 is journalled on trunnions 31 so that it may be revolved with respect to the container 25. The shutter over-' ceiving edge.

The container has peripherally and radially spaced keeper blocks 36 and 37 secured to end be turned.

cured to side bar 20 with arm 38 below the bar.

Secured to the pintle 39 above bar 20 is a crank arm 40. A link 41 is pivotallysecured to the outer endof crank arm 40. The other end of link 41 is pivotally secured by a pin 42 to a link 43. The other end of link 43 is pivotally secured to the bearing block on the bar 20. Pin 42 has a ball head nested within a socket 44 on the end of an actuating rod 45. By. moving rod 45 longitudinally, motion will be transmitted to arm 38 causing the latter to be turned. The particular mechanical motion between rod 45 and arm 38 is not pertinent to the inventive feature, and has been selected in order to produce a comparatively large throw of arm 38 with a short movement of rod 45. Other movements as found mechanically expedient may be employed. The arm 38 may be positioned-by means of rod 45 so as to be engageable by either step 37a or 37b of block 37 or by block 36 or to clear both blocks. Control means for moving rod 45 is provided and comprises a rocker having arms 46 pivotally secured to side bars 20. A yoke bar 47 of T form 'is shown connecting arms 46 so that the arms 46 and bar 47 form a unitary rocker referred to hereafter as rocker 46. Rods 45 are secured by ball and socket joints 48, one to each arm 46. Thus, when the rocker is moved, the rods 45 will be moved therewith and cause latch arm 38 to Pivotally secured to'yoke bar 47 is a link 49. Mounted on draw bar 23 is a pair of spaced bearing plates 50 between which a lever bar 51 is pivotally mounted. The bar 51 is pivotally mounted intermediate its ends and one arm thereof is pivotally secured to link 49. The structure is such that by rocking lever 51 forwardly, the rocker 46 will be swung backwardly and vice versa. A pull rope 52 shown in Fig. 1 is intended to be secured to the other armof lever 51 and the latter can only be rocked forwardly by means of the rope. To move the rocker 46 forwardly, a lever 53 comprising two bars is pivotally secured at one end to a bearing plate 54 mounted on draw bar 23. A pin 55 extends between the bars of lever 53, and extending between the bars with pin 55 in an elongated slot 56 is a connecting link 57 which is pivotally secured at the other end to yoke bar 47. A pull rope 58 shown in Fig. 1 is secured to lever 53. A forward pull on rope 58 swings lever 53 forwardly and link 57 in 'the same direction. This causes rocker 46 to be swung forwardly. Obviously neglecting the play allowed pin 55 by slot 56, movement of either lever 57 or 51 causes reverse movement of the other. v

When the container 25 is in skidding position as shown in Figs. 1 and 2, the latch mechanism for the container is in the position shown in Fig. 1A. Arm 38 will be disposed so that one end will register with keeper block 37 and the high step 37a thereof. Thus, when the scraper is drawn along the ground, step 37a engages arm 38 and revolution of the container is arrested with the material receiving edge 29 in skidding position. The shutter 32 is maintained in open position by mechanism later described. To attain digging position, lever 53 is pulled forward a slight distance, swinging rocker 46 forward and arm 38 with an end registering with step 375 as shown in Fig. 3A. This allows the container to revolve until arrested by step 37b engaging arm 38 so as to dispose the material receiving edge 29 in digging position as shown in Fig. 3. The next event is transporting of the load. The shutter.

32 is caused to be moved to closed position over the container 25 and coupled thereto so as to be revolved with the latter. The arm 53 is swung further forward to the-position shown in Fig. 4. This places the latch mechanism elements in the position shown in Fig. 4A, the arm 38 being out of line with both blocks 36 and 37 so that the container 25 and shutter 32 may be revolved as a drum and serve as a ground wheel. The material gathered in the container will be held therein and transported. The next event is' dumping of the load. The shutter 32 is arrested in the position shown in Fig. 5. The lever 53 is swung further forward to the position shown in Fig. 5 so as to position an end of the arm 38 in the path of block 36 and the latter may engage the arm 38.

-This arrests the container 25 with the material receiving edge 29 in position such that with shutter 32 open, the load will be dumped. The cycle of events is then repeated by first pulling arm 51 forward to a position returning the latch mechanism parts to the positions shown in Fig. 1A. The shutter-32 is caused to be positioned as shown in Fig. 1 and the container to be arrested in skidding position. 7

The shutter catch mechanism comprises an abutment plate 59 pivoted at 60 to the frame. It has abutment projections 61 and 62 spaced from one another. On the shutter is a lift latch 63, best shown in Fig. 7. It is pivoted at 64 to the shutter end wall 34 so as to have two arms. On one of the arms is a stop projection 65 arranged ter may be held in the positions shown in Figs.

1, 3 and 5 or released for revolution as shown in Fig. 4. Positioning of the plate 59 may be obtained from rocker 46 so as to be coactively positioned with the latch mechanism for the container. To this end, a connecting link 68 is pivotably secured to plate 59 and is slidably passed through the leg of yoke bar 47. A nut 69 is secured to the outer end of link 68 and a slidable washer 70 is mounted on the other side of the leg.

A compression spring 71 seats at one end against washer 70 and at the other end against plate 59 so as to form a compressively resilient link. An arm 72 fixed to plate 59 serves for independent operation of the latch mechanism. The parts of the latch mechanism are so related to the parts of the catch mechanism thatwhen the container 25 is in skidding position as shown in Fig. 1', abutment 61 will be engaged by projection 65 on latch 63 and the shutter held open. It will be noted that the engaging surface of abutment 61 is long enough to allow plate 59 to be rocked to the digging position without disengaging projection 65. Thus, in operation of the control mechanism arm 38 may be'passecl from skidding to digging posi- 35 tions and shutter 32 maintained open. It will be noted that in skidding position the pivotal axes oflink 49 and pin are in line so as to lock the control mechanism in this position from displacement by any thrust transferred from the .con-

49 tainer or shutter. Slot 56 allows the arm 53 to drop back in digging position with the axes and pin in line to maintain this lock relation. The

position of parts in the transporting event shown in Fig. 4 is such that the abutments'61 and 62 are 5 disposed on the outer and inner sides of the line of travel of latch 63 releasing the shutter 32 and may ride on the sides of rail 35.

In manipulating the mechanism to obtain transporting position, arm 72 is first pulled for- 5g ward to release shutter 32, which drops by its own weight to engagement with the ground and the arm 72 is then released. Compression spring 71 permits this movement without disturbing rocker 46. Upon release of arm 72, rail 35 prevents return of plate 59 to arresting position by reason of block 61 riding on rail35. The position of the latch mechanism parts is that shown in Fig. 3A. On the end wall 28 of container 25 is a keeper block 73 having a bevelled face for hook 67 to ride over and an engagement face 74 for the hook.

' Upon release of the shutter 32, it drops to engage the ground and hook 67 rides over block 73 to face'74 so that revolution ofcontainer 25 would carry along shutter 32. The shutter 32 tends to 55 roll on the ground, but .cannot overrun container 25 as the edge33a of the shutter will engage the material edge 29. Immediately after the shutter 32 is released, the arm 53 is moved forward to position rocker 46 as shown in Fig. 4, thereby releasing the container 25 for revolutionso that the container and shutter are revolved as a unit.

The load having been transported to dumping location, the arm53 is. pulled further forward to the position shown in Fig-.5. Abutment 62 will pass through the gap 35a rail 35 and be disi .which will-revolve until arrested by block 36 enposed for engagement by projection on latch 63 arresting revolution of the shutter 32. Projection 65 also will swing latch 63 to release hook 67 from block 73 and release the container 25 gaging arm 38; so that the container 25 is open with material edge 29 in dumping position.

The next event is skidding beginning another cycle. Ann 51 is pulled to restore the parts of the catch and latch mechanisms to that shown in Figs. 1 and 1-A. Plate 59 will be rocked back to a position such that abutment 61 will engage latch 63, whilearm 38 will be swung to engage 'step 37b of block 37.

Referring particularly to Figs. 8 to 15 inclusive, 90 a frame is indicated by 76. This frame is like that shown in Figs. 1 to 7 and has a draw bar 77. A container 78 of like structure to that of the embodiment shown in Figs. 1 to 7 has a material receiving plate 79 bordering an opening for material. Secured to the side walls of container 78 are trunnion blocks 80 best shown in Fig. 10. The trunnions 81 of blocks 80 are journalled in the side bars of frame 76. Joumalled on trunnions 81 isa shutter 82. Secured to a frame 83 within.100 the container 78 and midway between its ends is 4 an oscillating motor.

The motor '15 comprises a cylinder 84 having fixed abutments 85a and 85b diametrically oppo.ite one another and of sectoral form with a common center concentric with the bore of cylinder 84. concentrically disposed within the cylinder 84 is a shaft 86 having vanes 87 to sweep the spaces between abutments 85a and 85b.

Trunnions 81 are hollow as shown in Fig. 10 and have .hollow enlargements to which piping 88 and 89 are connected. Piping 89 is connected to a duct 89a extending around the cylinder between abutments 85a. and 85?). A port 89b in abutment 85a communicates with the duct 89a and the bore of the cylinder. A port 89c in abutment 85bcommunicates with the bore. Piping 88 communicates with a duct 88a having communicating ports 88b and 88c. The motor just described is an oscillating motor. When fluid pressure is admitted to piping 88. and the piping 89 is con-' nected to exhaust, the impeller 86, 87 will be rocked clockwise. By arresting the flow of fluid the impeller may be fluid locked in its arrested position. By reversing the flow of fluid the impeller may be turned in the opposite direction. Secured to shaft 86 is an arm 90 having its other end secured to shutter 82. Piping 91 is secured to the frame'76 and has an end 910 rotatably secured in block 80 and suitably packed. Piping 92 is connected to piping 89 in a similar manner. Piping 91 and 92 is extended along draw bar 77 and may be connected by suitable hose to a controllable source of fluid pressure on the tractor.

It is obvious that by controlling the flow of 35 fluid to the motor; the angular position of the shutter 82 with respect to the container 78 may be changed and the shutter may be closed or opened with the material receiving edge 79 in various selected positions. 1

A lug 93 is secured to shutter 82. An abut-' ment arm 94 is pivoted to a bearing block 95 on the frame 76. It has a roller to engage lug 93. Pivotally secured to' arm 94 is a link 96. A lever arm 97 is pivotally secured to the other end of link 96. Arm 97 is pivotally mounted on a pair of bearing plates 98. A double lever arm 99 is pivotally secured at one end to a bearing plate 100. Pivotally secured to arm 99 ha link 101 which is attached at its other end to rocker arm 50 94. Forward movement of lever arm 99 will swing rocker 94 forwardly and forward movement of lever arm 97 will swing rocker 94 backwardly. Thus, rocker arm 94 may be swung into the path of lug 93 to arrest movement of the shutter or may be swung out of its path to release lug 93.

In skidding position shown in Fig. 8, the arm 94 has been positioned to arrest revolution of the shutter. The motor has been operated and fluid locked to position the material receiving edge as shown with the shutter lug 93 resting on arm 94. To change to the digging event, the motor is operated to turn the container 78 clockwise and then is fluid locked in this position. Arm 94 is maintained in shutter locking position. The parts are then'in the position shown in Fig. 11. The transporting position is obtaine'd by first swinging lever arm 99 forwardly to move rocker 94 out of the path of lug 93, and the motor is operated to oscillate the impeller clockwise, thereby closing the shutter 82 upon the container 78 as shown in Fig. 12. The motor is then fluid locked and the shutter and container may then revolve as a drum. The next event, dumping is obtained by restoring'rocker arm 94 to arresting position'and operating the motor to cause the impeller to move counter clockwise to the end of the impeller stroke thereby positioning the parts as shown in Fig. 13. The restoration of parts to skidding position is apparent.
